Effects of nitrogen application and spraying of boron and manganese on growth traits of two potato cultivars

Abstract

In order to study the effects of boron and manganese micronutrients and nitrogen levels on growth traits of two potato cultivars an experiment was done using a factorial-split plot layout with randomized complete block design in three replications in 2012. The factorial combination of micronutrient×nitrogen was the main factor. Micronutrient application in 4 levels included: 1. control (m1) 2. boron spraying (m2) 3. manganese spraying (m3) 4. boron+manganese spraying (m4), and nitrogen application was in 2 levels of: 1. application of 100% of crop need to nitrogen (n1) 2. Application of 75% of crop need to nitrogen (n2) and the cultivar factor as sub-plot was in 2 levels of 1. Sprit cultivar (c1) and 2. Marfona cultivar (c2). Results showed that the effect of micronutrient on plant height, leaves number and shoot weight was statistically significant. The highest rates of mentioned traits was recorded in the treatment of m4 (boron+manganese). The effect of nitrogen application on plant height, leaves number and shoot weight was significant. The effect of cultivar on total traits was significant. Sprit cultivar was superior than Marfona with respect to vegetative traits. Considering the results Sprit cultivar in conditions similar to the region of this experiment may record higher rates of growth and yield characteristics than Marfona cultivar. Moreover dual application of boron and manganese can be resulted in remarkable improvement in agronomic traits of potato.

Implications of seed irradiation with γ-rays on the growth parameters and grain yield of faba bean

“…Yet this crop also needs a starter dose of N to stimulate N-fixation during early plant growth until N fixation provides adequate N (Abdul Rahman et al, 2018). Excessive N fertilization may delay the reproductive growth (Jafari-Jood et al, 2013); and consequently diminish grain yield (Manning et al, 2020). Thus, managing N inputs is essential to increase grain productivity while sustaining soils.…”

Effect of Cultivars and Spraying With Boron on Growth, Production and Quality of Potato Tubers

“…In addition to being involved in sugar transport to storage sites, it influences the production of nucleic acid (RNA), which is essential for protein synthesis. The synthesis of tryptophan and the control of glucose metabolism both rely on this mechanism [8]. Furthermore, maintaining a steady boron supply during a plant's growth is critical since it improves the plant's overall efficiency by making it more resistant to a wide range of viral, fungal, and insect diseases [9].…”
